Substrate Question.

Subject: Substrate Question.
by nad03 on 2012/9/8 12:52:35

I asked on another forum if there was a darker substrate that has the same buffering capabilities as coral sand.I was told that it is a myth that coral sand buffers the water and that if i added a commercial buffer to the water i could use any substrate that i wished.Is this true ?
